[Bug 53578] recent dapper kernels causing lockups on Dell Latitude D600

[anthony baxter]

Public bug reported:

The last two kernel upgrades for Dapper (starting with the one that came
as the same time as replacement ATI drivers - -25, I _think_ it was)
have led to massive stability problems on this Dell Latitude D600.

The hwdb ID is 3378cfe0d9fc6397152e6dbbf53268b7.

There's a couple of symptoms - sometimes, the box just locks up hard -
other times it locks up for 5-10s, then works again for a second or two,
then locks again, repeat. kern.log spits out (when it unfreezes)
messages like:

I thought it might be a hardware problem, but running the stupid little
Dell diagnostic program in a loop for hours didn't seem to trigger it -
I'm now running on the -23 kernel again, and it _seems_ to have made the
problem go away. I can provide more info if needed.
